Dr. Redwan N. Sajjad received the B.Sc. and M.Sc. degrees from Bangladesh University of Engineering and Technology, Dhaka, Bangladesh, in 2006 and 2008, respectively, and the Ph.D. degree from the University of Virginia, Charlottesville, VA, USA, in 2014, all in electrical engineering. During 2015-2017, he worked as a Postdoctoral Research Associate at Microsystems Technology Laboratories, Massachusetts Institute of Technology, Cambridge, MA, USA.
His expertise is in computational study of quantum-mechanical effects in carrier transport – namely the quantum transport in exploratory nanoelectronic devices, compact modeling, materials and device characterization. At MIT, he was part of a team that fabricated the world’s first sub-10 nm MoS 2 transistor and predicted its performance limits. His other works at MIT include impact of defects in Tunnel-FETs and characterization of group III-V semiconductor based Fin-FETs to study scaling issues. As a graduate student at UVA, he predicted - utilizing optics like behavior of carriers in graphene - the novel phenomena of transmission gap engineering. He also developed large-scale quantum mechanical simulation platforms for various materials such as 2D materials, nanowires and topological insulators. Dr. Sajjad has received multiple awards for his works on exploratory materials and devices and given numerous invited talks at various institutions.
He joined Bangladesh University of Engineering and Technology as an Assistant Professor in the Department of Glass and Ceramic Engineering in 2017.Current research interests:
Density Functional Theory (DFT) calculations, machine learning approach for high throughput material discovery, material to system level design, optimization and reliability study of photovoltaic systems, optical characterization of solar materials.
